-Claims. (01. 292- 40),

This invention relates to door stops and holders. One object of the invention is to provide a device of the character described whereby a socket of ordinary nonresilient tubular form may coast 5 with an improved resilient head, or in an improved manner therewith, greatly decreasing the cost of manufacture. 7

Another object of the invention is the provision of a device of the nature set forth having an improved socket mounting for'facilitating alinement of the head and socket, or to prevent the socket from being jarred loose by impact.

Another-object of the invention is to furnish a device of the type mentioned having a head and animp'roved mounting therefor; also improved associatedmeans to prevent noisy or jarring impingement of the stop.

A furtherobject of the invention is to construct a device of simple, inexpensive form, and which is 7270 durable, rugged, and eificient in use.

Other objects and advantages of the invention will become apparent as the specification pro ceeds;

With the aforesaid objects in view, the invention consists in the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated on the annexed drawing, wherein like parts are designated by the same reference characters'throughout the several views.

In the drawing: 1 I Figure 1 is a fragmentary horizontal sectional view showing a typical application of the invention. a I

Fig. 2 is a side view of a device embodying the invention, in disconnected position.

Fig. 3 is a central sectional view thereof in the engaged position for holding a door open. Fig. 4 is a plan view of a blank of which the head may be formed.

Fig. 5 is a sideview of a modified socket. The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the art to which this invention appertains, that the same 5 may be incorporated in several diiferent conmay be used as a releasable engagement means for various purposes. with different articles or objects. To illustrate the invention, the same is shown as, a door stop and holder which may be suitably reversibly mounted on a door-11 and a support or'wall 12. Thus the device may include a head 13, and a socket 14, preferably mounted on the door and wall respectively;

The socket 14'is sufiiciently elongated to form a stop. It may consist of a tube which may be open'at its ends, and is otherwise closed, so that the tubeis relatively rigid as distinguished from being resilient. Hence thenecessity for specially forming the socket is avoided, and the cost of manufacture kept low. The socket'may thus have a front opening 15 which may be slightly inturned or lipped at 16. to afford releasable engagement with thehead, and said opening is of fixed diameter. 1

The socket 14 is preferably resiliently mounted so that it or the mounting will not be subject to excessive jar if lateral impact against the socket should occur, as by any article or furniture in the room. Hence the socket may have a rear inturned annular flange 17, upon which may interiorly rest a resilient means such as a rubber washer 19. A fastening means or screw 20 may extend centrally through the washer into connectionwith the wall 12 for mounting the socket. The socket will thus be adapted to yield laterally both under impact and'for. alinement with the head, should the latter be slightly 'out of line with the socket. Y

Thehead 13 may be of a resilient character and, arranged to releasably engage the socket.

provision'of a blank 26 having a central portion 27 provided with radial extensions 28. This blank may be stamped into the cup shaped form, the extensions 28 becomingthe resilient tongues 25. In the portion 27, a central opening 29 may be provided for the passage of a fastener or screw 30 for mounting the head.

Within the head, there may be placed a spacer such as 31, this spacer being adapted to abut the front end wall 21 and the support 11 or assoids ciated part thereof. The screw 30 passes through this core and the latter is sufliciently small to afford a space between the same and the tongues 25 for deflection of the latter. By means of this spacer the rear edges 24 of the tongues are spaced from the support.

To prevent noisy or jarring contact of the socket and the support 11 in the engaged movement, a resilient means such as a rubber washer 32 may be placed between the support 11 and the head or core 31 thereof. The screw may extend through the washer, and the latter projects laterally beyond the edge of the socket to contact the edge of the socket when the door is swung open.

In Fig. 5 is shown a modification of a socket .33 which may in all respects be similar to that shown at 14, except that it is provided with a relatively large flaring entrance for easily guiding the head into the socket.

In this invention when the device is used to hold the door open, the head enters the socket with the tongues 25 locking at their edges 24 inside of the lip 16. These tongues may deflect in different degrees according to the alinement of the head and socket. The lip 16 is so arranged that upon exerting a suitable pull on the door, the head 13 is removed from the socket with the tongues springing together and sliding past the lip 16. Due to the resilient mounting of the socket, the same is accommodative to the socket. Should the door be slammed open, the member 32 takes the impact and avoids noise. By making the head 13 itself resilient, any nonresilient tubular socket may be used which is cheap to make. In stamping out the head, the same is simultaneously produced in the resilient form.

It will be appreciated that various changes and modifications may be made in the device as shown in the drawing, and that the same is submitted in an illustrative and not in a limiting sense, the scope of the invention being defined in the following claims.

I claim: 7

1. A door stop and holder including a metallic socket and a head of like material, said head having an end wall and a conoidal side wall, the side wall consisting of a plurality of closely spaced free ended tongues affording an opening therebetween opposite to said end wall, said socket being an elongated cylindrical spacer tube adapted to axially receive said head and having an end lip to detachablyengage said tongues at the free ends thereof, a core within the head seated against said end wall and spaced from said tongues in close relation thereto, said core projecting through said opening, and a fastener extending through said end wall and said core and adapted to secure the latter to a support for carrying the head.

2.
